Question 930347: Members of a movie rental club pay a $15 annual membership
fee and $2 for new release movies. Nonmembers pay $3 for new release
movies.
Write a system of linear equations that represents
this situation.
When is it beneficial to have a membership?

You can put this solution on YOUR website! members annual costs:
y = 2x + 15
---
non-members annual costs:
y = 3x
---
break-even:
2x + 15 = 3x
x = 15
---
up to 14 rentals per year the non-member option is cheaper.
at exactly 15 rentals per year both options cost the same.
for 16 or more rentals per year the member option is cheaper.
